20 pts! the image shown has two triangles sharing a vertex: what is the measure of ∠wzx, and why? y/2, because uvw is congruent to wxz y, because uvw isn't congruent to zxw y + 50 degrees, because uvw isn't congruent to zxw 130 degrees − y, because uvw is congruent to wxz

Angles V, U, and X are all marked with a single swish. That means that they all measure the same thing, 50 degrees. By the Triangle Angle-sum Theorem, all the angles inside a triangle add up to equal 180, so angle VWU = 180 - 50 - 50 which puts angle VWU as 80 degrees. Angle VWU is vertical to angle ZWX, and since vertical angles are congruent, then angle ZWX also equals 80 degrees. That means that angle WZX is 50 degrees. Hope that helps because I'm having a hard time trying to decipher what your answers are. They are a bit crammed together.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
